IMPROVEMENT IN MLDS FOR CEMENT BURlAL-CASES.

Specifioation 'forming art of Letters Patent N0. 133,684, dated Dccember3, 1872.

T0 all wh'om z't may concern:

Be it known that I, PLATT B. VIELE, of

4R0chester, in the oounty of Monroe and Staate of New York, hzweinvented. a certain Improved Flask for Molding Burial-Oases and SimilarArtioles, 0f which the following is a sp ecifioation:

The natura of my invention consists in a -peculiarly-conslzructed mold01 flask, in which die case, which is preferably made of hydraulicceuient, is formed.

Figure l is a vertioal longitudinal section of 1 the lnold after beingfilled. Fig. 2 is an inverted view of the sanie, having the sole-plate Aremoved. Fig. 3 is a side elevation of the ease with the oap O. Fig. 4is a transverse section of the latter.

-A represents the sole-plate of the fiask or mold; B and B, the endsections ofthe core;

D und D, the side seotions. E, E, and. E and F, F, and F and G, G, and Gconstibe locked together ab the .corners by ordinary snap-flask hooks.The outer. Walls are as much higher than the core as the thicknessdesired for tlle bottom c of the c2tse, as shown in Fig.- l. The sideam]. end walls of the core, B and B am]. D and D, are divided vertically011 a bevel, as seen'atf, Fig. 2, which permits seotion D 011 eit:herside and sect ion B 011 either others. B and B are provided with aledge, b, for the support of the outer end of E, E,

' und E and F, F, and- F, their opposite ends being supported by therests d, Fig. l. The central sections G, G, and G rest; upon the rihs q:'lhe bottom sections are provided with handles h.

After the mo1d is fi1led there is a follower board or plante,represented by the dotted lines n, Fig. l, placed on the flask, which isthen turned over or inverted, and 'the sole-plate A is removed, whichre1eases the sections of the core anti the outer alls of the flask.Seotion G is. then removed, after which G am]. G may be partia-lly drawnin am}. lifted. ofl. E

and.F are also drav vn centrally and lifted out. Then E and E a-11d Fand. F are drawn away from the sides and ends and removed. The

inner end of section D on either side is then Swung away from the cementand removed.

Seotions D are then taken out, when the ends B and B may be similarlyremoved. The outer alls H and I may be removed in the same manner as anyordinary snap-flask.

The object of making the mold-core in soveral parts, as shown, is that asolid core with thata amount of surfa-ce could not be withdrawn fron1the thin molded oase without tearing the bottom c up With it. Soction G,being sma1l, exposes but litt1e surface to the cement, and therefore canbe readily lifted out, am]. each 0f the others may then be moved. moreor less 0n the surface 0t' the green oement, which permits them L"O beremoved witliout lifting or otherwise disturbing the cenieni; underthem. 'lhe side walls of the core and flask may be started in the samemanner.

It Will be seen that this flask provides fo1' moldin g the case in aninmrted position, which is bolieved 170 be about the 0nly praat-ical wayof producing it when made of hydraulio cement 01' similar material, assuch has to be tamped. The sides and bottom are only accessible in thisposition in a ma-nner 130 form or fill the sides first, then the bottom.The whole material is thereby thoroughly united in one homogeneous mass,leaving 110 sezuns 01 slack places in the cement. end 130 be removedwithout difstutbing the I olaim aus my inventionl. A mold for oementburial-cases, made in sections B, B, D, D, E, E, E, F, F, F, andpurposesshown am]. described.
